Failed internal HDD in MacbookPro. Replaced drive, Old drive appears working

My MacbookPro's Seagate drive failed to spin up about a week ago. I realized the thing was not 5 years old so not a big surprise. I don't have any fully valuable data that would make it worth paying for a fix, but I do have it now psuedo working (after a nice long chill in the freezer). I hooked it up to a SATA harness to USB. It is recognized in Disk Manager in windows 7, but will not initiate due to an I/O error. The drive had Windows 7/ OSX 10.5.8 with MBR partitioning I believe. I now have Windows 7/OSX 10.8.4, but the drive won't show up under OSX either, in finder or Diskutility.

Advice?
tl;dr
-Old drive crashed with bootcamped OS's
-New drive in computer, old drive frozen and hooked up to SATA harness
-Shows up in W7 in disk manager, but will not initialize
-Not shown in disk utility (or finder) in OSX 10.8

(I'm also aware freezing can sometimes do damage, but for obvious reasons let's all assume that isn't the case until I try some other stuff)

The disk shows in Disk Management, but is in "Offline" mode and cannot be initialized. My current HDD in the laptop has enough freespace on the windows partition to fit the entirety of the old drives data/image. Would i be able to use a cloning program to extract the image onto a drive without formatting, or would it have to be a separate drive?

Also, with the USB boot are you saying that it might not be intializing because it has boot sectors on it? If so, would I be able to use an OSX (10.5) Install disk and use the liveboot diskutility on that?



And while it's not important, I am fully aware to backup important data, but all I really do is gaming on it, and the documents and such for school i have backed up to cloud. Is it sad the only thing I'm really missing is my collection of 300+ wallpapers?
